Build a bigger vocabulary, one word at a time.

​

FlipDict is a focused, no-nonsense vocabulary builder for native speakers, advanced English learners, writers, and anyone who wants to know more words. Flip through a real dictionary of 63,000+ English words, tap the ones you don't know, and let spaced repetition do the rest.

WHY FLIPDICT IS DIFFERENT

​

Most vocabulary apps make you study word lists someone else picked. FlipDict gives you the whole dictionary and lets you build your own. Browse pages like a real book, tap interesting words you want to learn, and review them later with proven spaced repetition.
